The document contains multiple choice and short answer questions about modeling combined functions. Some key points covered include: - Sound intensity is dependent on frequency and wavelength. - Combined waveforms need to be regular and repeating to sound good together. - A skier's height over time can be modeled by combining exponential and sinusoidal functions. - Predator-prey relationships and interfering waves can be modeled with combined functions. - Combining functions f(x)=(x^2) and g(x)=(x+6) results in the composite function y=f(g(x)). - C# has a higher frequency than C. - Modeling combined functions requires a minimum of 1 or 2 functions
